Abstract

La présente invention se rapporte au domaine des communications. Sont divulgués un procédé et un appareil pour déterminer une priorité de mise en file d'attente et un dispositif de communication et un support de stockage, qui sont utilisés pour déterminer, selon des informations de QoS et des informations d'état de transmission, une priorité de mise en file d'attente d'un paquet de données à transmettre, afin d'améliorer les performances de transmission. Le procédé de détermination d'une priorité de mise en file d'attente comprend : une extrémité d'envoi qui acquiert des informations de QoS d'un paquet de données à transmettre dans une pile de protocoles de couche supérieure et acquiert des informations d'état de transmission correspondant au paquet de données lorsqu'il est transmis dans la pile de protocoles de couche supérieure ; et l'extrémité d'envoi qui détermine une priorité de mise en file d'attente du paquet de données dans une zone tampon sur la base des informations de QoS et des informations d'état de transmission. De cette manière, une extrémité d'envoi détermine, en combinant des informations de QoS à des informations d'état de transmission qui sont renvoyées en temps réel, une priorité de mise en file d'attente d'un paquet de données à transmettre. Étant donné que les informations d'état de transmission sont une considération de l'état de transmission actuel d'un canal et du paquet de données, la performance de transmission du paquet de données est efficacement assurée au moyen du procédé pour déterminer de manière complète la priorité de mise en file d'attente du paquet de données sur la base des informations de QoS et des informations d'état de transmission.
